Today，the auto industry must move away from the traditional trial-and-error methodology of crash testing and embrace simulation-based design. To help designers and engineers achieve this take advantage of the latest simulation technology,ESI and Intel hace been working to bring leading simulation software to market that will help companies to innovate faster by reducing the need for real prototypes through collaborative engineering.
Specifically, the research and development teams at ESI and Intel have been working to optimise ESI's Visual Environment V3.0 to take advantage of Intel's multi-core processors,using software tools(Intel VTune and Intel Thread Checker).
This joint Intel/ESI development means users can now enjoy enhanced computing performance, better cost efficiency and more choice with regards to the size of the crash model.
The development also provides more accurate simulations. Data-processing time is up to 2.79 times faster for huge crash models(10 millon elements) on Visual Environment V3.0, as optimised on the latest multi-core Intel Xeon processor.
ESI's integrated solution underpins a proven engineering simulation environment based on openness and extended interoperability with tier CAE and ESI's solvers. This sharing of resources between ESI and Intel amounts to a significant step forward in realistic simulations that use a minimum of 10m elements for crash simulation.
The first results point to a performance boost of up to 250% in data processing from VE 2.5 to the VE 3.0 optimised on the latest dual-core Intel Xeon Processor 5100 Series , as well as more than 4GB allocated in memory using Windows XP 64bit on the latest multi-core Intel Xeon processor . These outstanding scores produce more accurate simulations , mainly due to a refined model which allows the investigation of critical zones, such as that made by a German carmaker using the multi-scale coupling option of Pam-Crash 2G to introduce detailed information results from casting into crash-model simulation.
"Intel is very pleased that, through our collaboration, ESI Group has used our software development tools to optimise Version 3.0 of Visual Environment to provide new levels of performance on our Dual - Core Intel Xeon Processor 5100 Series ," says Stephane Negre, Intel EMEA global software relations manager . "ESI Group's customers can now load models of millions of elements .We will carry on working with ESI Group in developing new platforms to anticipate the future customer's needs."
"This partnership with Intel enables ESI Group to overcome environmental limits by opening up new opportunities to solvers to deliver realistic simulations . Up to now ,our customers were obliged to build compute models dedicated to several types of crash simulation . Thanks to these excellent results , engineers can use a unique crash model that covers the crash and safety simulation domain as a whole ," says Jean - Louis Duval ,ESI Group worldwide business manager for enterprise integrated solutions .
The next step will be to take advantage of Intel multi-core technology in order to provide a multi-thread environement, which will deliver the best in -class performance solution.

今天，汽車工業(yè)必須擺脫傳統(tǒng)的以反復(fù)試錯為方法的碰撞實驗，接受基于仿真的設(shè)計。為了幫助設(shè)計師和工程師達到這個目標，并利用最新的仿真技術(shù)，ESI集團和英特爾公司一直致力于把領(lǐng)先的仿真軟件投入市場，這將有助于公司加快創(chuàng)新速度，通過工程師協(xié)作減少對真實原型需要。
具體而言，ESI集團和英特爾公司的研發(fā)團隊利用英特爾性能分析器（Intel VTune）和英特爾線程檢查器（Intel Thread Checker）等軟件工具，一直在努力優(yōu)化設(shè)計ESI集團的視覺環(huán)境軟件3.0版，(ESI's Visual Enviroment V3.0)，以利用英特爾公司的多核心處理器(Intel’s multi-core processors）。
此次英特爾/ESI的聯(lián)合開發(fā)意味著用戶現(xiàn)在可以享受更強的計算性能，更好的成本效益和對于碰撞模型尺寸的更多選擇。
這項開發(fā)也為用戶提供了更為準確的模擬。由于在最新的多核英特爾至強處理器（multi-core Intel Xeon processors）上優(yōu)化，在視覺環(huán)境3.0版（Visual Environment V3.0）中，大型碰撞模型（1000萬個單元）的數(shù)據(jù)處理時間可提快至2.79倍。
WSI的整合式解決方案基于CAE和ESI的解決者之間的開放性和擴展互操作性，加強了行之有效的工程仿真環(huán)境。使用最低限度的10兆單元來做碰撞仿真，ESI和英特爾的這次資源共享等同在真實的仿真中向前邁出的重要一步。第一項成果是，在最新的雙核英特爾至強處理器5100系列（dual-core Intel Xeon Processor 5100 Series）上優(yōu)化，以及在有超過4GB分配內(nèi)存、采用windows XP64位、最新的多核英特爾至強處理器（multi-core Intel Xeon processor）上優(yōu)化，從視覺環(huán)境2.5版（VE2.5)到視覺環(huán)境3.0版（VE3.0)，在數(shù)據(jù)處理上性能提升高達到250%。這些顯著的成績產(chǎn)生更加準確的模擬，這得主要功于允許關(guān)鍵區(qū)域調(diào)查的精確模型，例如像德國汽車制造商做的那樣，采用Pam-Crash-2G軟件（ESI推出的一個軟件，是一個應(yīng)用于沖擊、碰撞和安全性專業(yè)領(lǐng)域的虛擬測試解決方案）中的多尺度耦合選項，來引入鑄件的詳細信息到碰撞模型仿真。
“英特爾公司非常高興地看到，通過我們的合作，ESI集團已經(jīng)利用了我們的軟件開發(fā)工具，在我們的雙核英特爾至強處理器5100系列（multi-core Intel Xeon processors 5100 Series）上，來優(yōu)化3.0版的視覺環(huán)境（Visual Environment），以提供新水平的性能?！坝⑻貭枤W洲、中東和非洲公司（Intel EMEA)全球軟件事務(wù)經(jīng)理斯蒂芬 尼格（Stephane Negre）說，”ESI集團的客戶現(xiàn)在可以擔負數(shù)百萬單元的模型的仿真。我們會繼續(xù)努力做好工作，與ESI集團開發(fā)新的平臺，以搶占未來客戶的需要?！?SPAN lang=EN-US>
”和英特爾的這一伙伴關(guān)系，通過開辟新的機會給解決者來交付真實仿真，使得ESI集團客服環(huán)境的限制。在此之前，我們的客戶不得不建立計算機模型，專責集中類型的碰撞仿真。而現(xiàn)在由于這些出色的成績，工程師們可以使用一個唯一的涵蓋了碰撞和安全仿真領(lǐng)域，并作為一個整體的碰撞模型。“ESI集團負責企業(yè)集成化解決方案的全球事務(wù)經(jīng)理珍妮 路易斯 杜瓦爾（Jean Louis Duval）說。
下一步將充分利用英特爾多核心技術(shù)，以提供一個多線程環(huán)境，這將得到實現(xiàn)最好的、一流的性能的解決方法。
